Battlefield Damage Level Assessment for Submarine Torpedo Weapon System Based on Evidential Reasoning Algorithm

There is a growing need to make submarine maintenance plans and distribute repair missions based on the research of damage level assessment. Considering the index of torpedo weapon system and the characteristics of damage evaluation elements, a damage level assessment model based on evidential reasoning(ER) algorithm for multiple attribute decision analysis was presented. The model can combine multiple basic assessments of damage elements, deal with quantitative or qualitative information with uncertainty and subjectivity, and calculate the confidence degree of uncertainty. Therefore, it is an effective tool for the evaluation of submarine battlefield damage level. The evaluation results show that the model can deal with the information with uncertainty during the course of level assessment, and benifit repair decision-making.
